A 19-year-old man and another in his 20s are now in custody as persons of interest over a carjacking that killed three young siblings in Philadelphia on Friday.

Police in North Philadelphia say they used finger prints from the stolen SUV - which rammed into a family selling fruit for their church - as well as a bloody t-shirt found near the crash scene, to locate the suspects.

Neither has been named and charges have not been filed, but their capture comes after authorities posted a $110,000 reward was posted for the pair.

'You can run but you can't hide but for so long. You've got to pay for what you done,' the victims' uncle, Antonio Moore, told NBC Philadelphia.

Three children were killed and three people critically injured when a hijacked car lost control and hit a group of people near a fruit stand, according to police

The men are accused of killing 15-year-old Keiearra Williams, 10-year-old Thomas Reed and 7-year-old Terrence Moore.

The two suspects fled on foot after crashing the stolen car Friday morning at a North Philadelphia intersection.

They had first carjacked a real estate agent at gunpoint and later forced her into the back seat of her SUV, authorities said.

The
45-year-old agent was also hospitalized afterward, as was a 65-year-old
woman helping the family with the fruit stand. Their names weren't
being released, and their conditions weren't immediately available
Saturday.

'All they said was
my grandma got hit, and there were bodies everywhere,' Sakina Brown,
granddaughter of the 65-year-old victim, told The Philadelphia Inquirer.

'My heart was about to jump out of my chest.'

She
said her grandmother had seen the vehicle coming and tried
unsuccessfully to get out of the away. She suffered a broken ankle and
bruised sternum when she was struck. The group held the fundraiser every
week to raise money for a church effort to turn the corner lot into a
playground, Brown said.

Eyewitnesses
who rushed to help the injured described a gruesome scene. One woman
rushed to the boys, finding one with only a light pulse and the other
with none.

The 10-year-old died at the scene. The other two were pronounced dead at hospitals.

'Three innocent children had their lives taken,' Philadelphia Homicide Capt. James Clark said of the siblings.

The
reward for the suspects' arrest has reached $110,000, thanks to
contributions from the city and the Fraternal Order of Police. Police
have also asked nearby businesses for surveillance videos, and were
getting tips from the public.

'There
are no words to describe how I feel right now,' said police
Commissioner Charles Ramsey, 'but we do need to find these two guys'.

Police
believe the suspects may have blown a tire as they turned a corner at
high speed. The car ended up in a wooded area, its front end smashed
against a stand of trees, about a mile from the carjacking scene.
